A Soviet-era spacecraft that failed to reach Venus is due to crash back to Earth this week
Context:
A piece of a Soviet-era spacecraft, Cosmos 482, which failed to reach Venus over 50 years ago, is predicted to reenter Earth's atmosphere around May 10. The spacecraft, believed to be a probe or 'entry capsule' designed to withstand Venus's harsh conditions, might survive the atmospheric reentry due to its substantial heat shield. Though the risk to people on the ground is minimal, with a 1 in 25,000 chance of causing significant damage, precautions are advised if it lands on dry land due to potential hazards like leaking fuels. The Soviet Space Research Institute's Venera program, responsible for launching the spacecraft in 1972, was part of the space race with the United States. The incident underscores the importance of ongoing efforts in space debris mitigation, as uncontrolled reentries can pose risks even decades later.
Dive Deeper:
Cosmos 482, a Soviet spacecraft intended for Venus, malfunctioned and is set to crash back to Earth this week, posing a small risk due to its heat shield, which could allow it to survive reentry.
The spacecraft is believed to be a probe or entry capsule from the Venera program that was designed to withstand the extreme conditions on Venus, such as high pressure and temperature.
While space debris frequently reenters Earth's atmosphere, most disintegrate due to friction; however, Cosmos 482's robust construction means it could survive and hit the ground.
The chance of Cosmos 482 causing significant harm is low, with a probability of 1 in 25,000, but its potential landing area spans across many major landmasses, increasing vigilance in those regions.
If Cosmos 482 lands on dry land, it is crucial that bystanders avoid contact due to the risk of hazardous material leaks, and authorities should be notified immediately.
The incident highlights the necessity for the space community to continue improving debris mitigation strategies, as old spacecraft can remain in orbit for decades, posing long-term risks.
Under the 1967 Outer Space Treaty, Russia would retain ownership of any surviving debris, which emphasizes international legal obligations and recovery rights for spacefaring nations.
